I have been running the past 9 months. It has helped me lose alot of weight. I'm in the conditioning stage now though, and must be able to do a 1.5 mile run in no more than 14 minutes, 30 seconds. (14:30) I did a test run last night to see where I'm at, and I did it in 16 mins 35 seconds. I'd like to reach my goal by mid december. I run about 4 times a week. So, per week, what is a good amount of time to be knocking off my time? I figure about 20 seconds a week at least. Within 6 weeks I should have those 2 minutes shaved off, with plenty of time to spare to get even better. Is this a realistic rate, do you think?
